GS700TS Smart Switch Software Administration Manual The CST Port Configuration screen contains the following fields: • Interface - Displays the port or LAG for which the STP information is displayed. • STP Status - Select the STP status on the interface. The possible field values are: - Enable - Enables STP on the interface. This is the default. - Disable - Disables STP on the interface. • Fast Link - Select the Fast Link state on the interface. If Fast Link mode is enabled for a interface, the Port State is automatically placed in the Forwarding state when the port link is up. Fast Link optimizes the STP protocol convergence. The possible field values are: - Enable - Enables Fast Link on the interface. - Disable - Disables Fast Link on the interface. This is the default. • Port State - Displays the current STP state of a port. If enabled, the port state determines what forwarding action is taken on traffic. Possible port states are: - Forwarding - Indicates STP is enabled on the port, and the port is forwarding packets based on the STP topology. - Disabled - Indicates STP is currently disabled on the port. The port forwards traffic while learning MAC addresses. - Blocking - Indicates the port is currently blocked and cannot forward traffic or learn MAC addresses. - Listening - Indicates the port is in Listening mode. The port cannot forward traffic nor can it learn MAC addresses. - Learning - Indicates the port is in Learning mode. The port cannot forward traffic, however it can learn new MAC addresses. • Speed - Displays the speed at which the port is operating. • Path Cost - Enter the method used to assign default path cost to STP ports. The possible field range is 1 - 200000000. The default path cost assigned to an interface varies according to the selected CST configuration method (Hello Time, Max Age or Forward Delay). • Priority - Select the port priority value. When switches or ports are running STP, each is assigned a priority. After exchanging BPDUs, the device with the lowest priority value becomes the Root Port. The port priority has a range of 0-240 in increments of 16. The default value is 128. Configuring Switching Settings v1.0, June 2009 4-36

Configuring Switching Settings

v1.0, June 2009
The CST Port Configuration screen contains the following fields:
Interface
– Displays the port or LAG for which the STP information is displayed.
STP Status
– Select the STP status on the interface. The possible field values are:
Enable – Enables STP on the interface. This is the default.
Disable – Disables STP on the interface.
Fast Link
– Select the Fast Link state on the interface. If Fast Link mode is enabled for a
interface, the Port State is automatically placed in the Forwarding state when the port link
is up. Fast Link optimizes the STP protocol convergence. The possible field values are:
Enable – Enables Fast Link on the interface.
Disable – Disables Fast Link on the interface. This is the default.
Port State
– Displays the current STP state of a port. If enabled, the port state determines
what forwarding action is taken on traffic. Possible port states are:
Forwarding – Indicates STP is enabled on the port, and the port is forwarding packets
based on the STP topology.
Disabled – Indicates STP is currently disabled on the port. The port forwards traffic
while learning MAC addresses.
Blocking – Indicates the port is currently blocked and cannot forward traffic or learn
MAC addresses.
Listening – Indicates the port is in Listening mode. The port cannot forward traffic nor
can it learn MAC addresses.
Learning – Indicates the port is in Learning mode. The port cannot forward traffic,
however it can learn new MAC addresses.
Speed
– Displays the speed at which the port is operating.
Path Cost
– Enter the method used to assign default path cost to STP ports. The possible
field range is 1 - 200000000. The default path cost assigned to an interface varies
according to the selected CST configuration method (Hello Time, Max Age or Forward
Delay).
Priority
– Select the port priority value. When switches or ports are running STP, each is
assigned a priority. After exchanging BPDUs, the device with the lowest priority value
becomes the Root Port. The port priority has a range of 0-240 in increments of 16. The
default value is 128.
